Fuel gauge not working

i removed the kick panel today. i traced the wire coming from above the gas tank in the trunk (blue) and it went up and over the left rear fender, down along the bottom of the door and came to a plug behind the kick panel. i disconnected the plug and i grounded the blue wire that continues up to the gauge cluster.....i was excited to see the fuel gauge move for the first time. So i know the gas gauge works (it pegged itself up to full), and i know the voltage regulator works. i plugged the plastic plugs back together turned the key and the fuel gauge doesnt move. does this mean the sending unit is bad? or does it mean i need to replace the wire that is going from the fuel tank (inside the trunk) to the plastic plug behind the kick plate?

The first photo is what i have down at the fuel tank......grounding strap looks good, i scuffed all underneath it so its getting good metal to metal contact. the wire right next to it appear to be black.....i sprayed degreaser and scrubbed it just to be sure. is that the same wire that comes out the top and into the trunk which is blue? is it one continuous wire?

IF you unplug it at the tank and ground it and it goes to full... The sending unit has the issue.
